To all whom it mag/concern: y Y

Be itvknown that I, MIKE SHUK'I'IES, Jr., a citizen of the United States, yresiding at Johnston City, lin the county of lVilliamson and State fof Illnois,'haye inventedgcertain g new and useful Improvements in Trolley,

Controls, of which thev following is -aspeciiication. s i y l This invention has relation'to trolley .pole attachments land lhas for an object `to ypro-` vide means of a vresilient nature forretaining'the trolley pole lin afpo'sition'to insure' engagement `of the trolley `wheel with the wire, and means operable automatically when 'the trolleypole `movesvupward owing to disen'gagement'of jthe'tro'lley wheel from the wire to release the resilientmeans whereby-to permit' the trolley pole l,to ydrop .to a position wherein the possibility "of injury to the lt'rol'leypole for other 'parts of the Vsystem is obviated.

lAnother object of the invention is to 'provide a trolley pole ycontrolling means in the nature v"of a casing to 'be secured upon ythe roof ofthe car, adapted to support the trolley ypole with a vresilient means such as `a springY engaging vthe Atr'foll'ey.pole to retain the trolley vlwheel in engagement with the wire, la trigger means acting `to retain the spring lunder tension, whereby in fthe vevent that the wheelbecomes `disengaged from'thel trolley to lpermit the trolley polev vto move upward, the trigger may be thus engaged by the pole to causerelease of'thejspring,V

parts to be hereinafter more fully describedand particularly set vforth `in kthe .appended claims. Y 'In the accompanying ldrawings in vwhich similar and `corresponding parts are designated by the lsame characters of reference TROLLEY-CONTROL.

throughout Athe several views which they appear:n f I Figure 1, is a view inside elevation of a trolley poile and controlling means therefor constructed in accordance with my invention.

Fig. 2,"is a view of the trolley pole supporting and controlling means in longitudinal section, and

Fig. "3, is a View in vertical `transverse section taken on the line 3 3 of the preceding gure.

`With reference to the drawings, 10 indi# cates .a'casing having a longitudinally eX- tending bore 11 therein. A pair of upstanding ears 12 Vare formed at one end of the vcasing the 1 space between the same communicating with' a bore as is shown. Movable withinfthe bore 11 isa block 13 hav- `ingfoppositely extending :trunnions 14 which extend through `longitudinally extending slots 15 in the sides :of `the casing. The block 13 vis formed with sa transverse Opening .to receive` a bolt 16 which passes loosely therethrough, an eye 17 being formed upon one end of the ;bolt,.and a nut 18 applied to the Iother Yto bear against the block.

`lMounted upon the casing adjacentV that n end supporting the ears 12 is a trolley pole indicated at 119 'pivotally mounted upon a bolt 20. A bolt v21 .is mounted in the rtrolley pole iat` a ipoint above the fulcrum thereof,V

and one end of a heavy coil vspring 22 is connected `to `said bolt 21, the 4other end eX- ten'di'ng into the bore ofthe casing for connection 'to vthe eye 17 of the bolt 16.

' Extending upwardly from' an intermedi ate point of the casing'and at the sides thereof, are two arms Q3, .the same being. pivotally 1mounted for movement about points 24 located adjacent `the base of the casing with the Vupper end of said arms bent toward each other and merging into a lever 23 lwhich is pivotal'ly connected to the upper end` of a pair l.ofarms 25 forming a `part of the trigger or yretaining mechanism. (See Fig. The yarms 25, of which two are providedextend `downwardly in diverging relation from 'their point of connection to the lever 28 at -fopposite'sides of the casing and are connected together *by means of the, oppositely extending trunnions 14 of the block which pass through openings in said arms 25. The trunnions 14 after passing through-the openings ofthe arms v25 also enter openings inthe forward end of linksthat purpose to secure the links 26 and arms 25 against displacement.

nature of a pair of levers 28 pivoted at a point intermediate their ends Aupon a trans'- versely extending bolt 29 which is supported upon the ears12, one ofsaid levers 28 being provided at each side of the'casing and engaging against the outer, faces of the ears. The levers 28 areY disposed in a normally inclined position with their lower ends aperturedv to receive rivets -or the like 30 which serve to engage the rear ends of the above mentioned vlinks 26 for pivotal connection thereto;y The lower `ends of the levers 28 adjacent the point of connection to the links 26 are formed with angularly extending extensions 31 which extend upwardly, with the upper terminals thereof connected by means of braces 32 with the Y intermediate portion of the levers 28 so as to define a triangular structure at the lower endl of said levers to provide rigidity. The upper ends of the extensions 31Vare connect.-

ped. together by means of` a transversely extending bolt 33'which also serves as a rest e for .thetrolley pole in a manner which will be presently obvious. It will be noted that the trolley pole 19 operates between the' levers 28V and between the bolt 33 and the rear end of the casing, the lower ends of the levers 28 extending beyond the casing as shown in the drawings. Mounted .upon the transversely extending bolt 29 mentioned above is an angular member forming a trigger comprising al horizontally extending arm 34 and a riglltangular, upwardly extending arm 35 formed integrally therewith, the upper .terminal of said arm 35. be ing bent rearwardly to form the pole enga"- ing member 36, the same .being prefercbljy bifurcated.l The horizontal arm 34 extends toward the forward end of the casing, between the arms 23 and '25 and beneath a transversely extending bolt or rod 37 connectingthe arms 25 at a point above the casing. The forward end of .the arm 34 is .formed with a depressed or ol'lset portion 38 in which to receive the bolts 37 when the mechanism is in an operative position. A

coil spring 39 is further provided, being connected at one end to the arm 34 and at its opposite endto the upper ends of the levers28'which converge above the casing andare connected together by vmeans of a,v

rivet 40 to which the spring is connected.

In operation, to place the spring 22 under tension so as to cause the same to act `to urge the trolley pole upward lto ,engagethe the spring 22 lunder strain.

inthe casing in a forward direction toplace The forward til .the bolt 37 .connectingthearms4 25 is brought into aposition beyond the forward ends of the arms 34 ofthe trigger whereby spring39 may act to move the arms 34 upward slightly and securely seat the depending portion 38'of the arms adjacent the bolt 37. By momentarily releasing the trolley, the parts will be held againstreturn to the position to which they have beenmoved. The, spring 22 will now be `under strain and the: trolley pole 19- will be urgedupward andthe trolley wheel retained in engage ment with the wire in the usualwmanner. In

the event that the trolley wheel becomes dis.-v engaged, from the trolleywire the pole will .fly upwardy under tension of the springY 22 until forcibly brought into engagement .with

the-end 36 ofthe upwardlyextending arms 34 of thetrgger. The forward end of the arm 34 will then be moved down slightly to a degree sufficiently to -disengageg the bolt 37 of the arms'25 `thereby releasing the spring 22 which becomes immediatel'yinefV vfective'or expanded by rearward movement ofthe block13. The ltrolley pole being no longer supported falls downward until its movement is limited by engagement with the bolt 33 and the pole is thus supported in a lowered position wherein the vpossibility of contact .with the, trolley wire support is prevented.` It will be noted Ythat `when the trolleypole engages the said bolt33 the weight of the pole will causethe levers 28.

While I have illustrated and described my invention with somedegree of particular-ity, I realize that in-'practice-.various alterations thereover maybe made,.and I therefore. de-V sire to reserve the right and privilege of changing the form of the details of construction, y or otherwisealtering the arrange; ment of the correlative parts without de-v parting from 'the vspirit of the invention or the scope of the appended claims Y p Having thus l described my invention, what I claim as new and desire to secure by Letters Patent is l, A trolley pole control and support including a casing, a trolley pole pivotally mounted thereon, la pair of spaced levers pivotally mounted vat points intermediate their ends upon the casing, a bolt connecting adjacent ends of said levers to afford a support for the trolley pole in its lowered position, a coil spring within the casing having one end connected to the trolley pole, a block slidably mounted in the casing to which the other end of the spring is secured,

links connecting said levers'with the block, a pair of `arms connected' to the block, a: transverse bolt carried Vby said arms, a bell Y crank member pivotally mounted on the casing to engage the bolt to'retain the block in shifted positionpto tension the spring, and

a coil spring connecting saidarm with the levers, the bell crank member being engageable by the trolley pole when suddenlyVU moved upward to release the bolt whereby the block may returnto normal position to render the spring effective.

2. A trolley pole supporting andvVcontrolling device, including a, casing, a trolley pole mounted thereon,a coil spring connected at one end to the trolley pole, a block slidably mounted in the casing to which the other end of the spring is connected, a

pair of upstanding arms pivotally mounted upon the casing at opposite sides thereof, a pairv of depending arms pivotally connected to the upper ends of the first mentioned arms, and havingr their lower ends pivotally connected to the block, a bolt connecting the Vsecond mentioned arms, a bell crank having one arm extending beneath the bolt for engagement vby the bolt, when the block is shifted to tension the spring, and means operable upon downward -movement of the pole to shift the block.`

In testimony whereof I affix my signature in presence of two witnesses.
